Is this doable ? For example to use tunnel from he on my router settings and the rest pcs on my home network to be able to get automatically an ipv6 address? It has stateless and stateful settings page . The stateless requires only the ipv6 address of the router and the dns servers .

Remote ipv4 address :216.66.87.14Remote ipv6 address: 2001:470:1f1a:198::1Local ipv4 address: My current ipv4Local ipv6 address: 2001:470:1f1a:198::2Primary Dns Server: I will use the one provided from HE , in this case is 2001:470:20::2
